Winter

Winter is one of the four seasons of temperate zones. In both hemispheres, winter begins on the day of the year which has fewest hours of daylight, "winter solstice", and ends on the following equinox. In the Northern Hemisphere, depending on the year, it begins between December 20 and 21 and ends on March 20 or 21. In the Southern Hemisphere, depending on the year, it begins between June 20 and 23 and ends on September 22 or 23.[1][2] From a meteorological perspective, winter is the season with the shortest days and the lowest average temperatures. It has colder weather and, especially in the higher latitudes or altitudes, snow and ice.
